RICHARD A. MILLER SELF-LOCK TYPE ADJUSTABLE WIDTH BEDFRAME The present invention relates to adjustable bedframes and more particularly to an improved adjustable frame construction in which the frame may be readily adapted for use with different size bedding.

BACKGROUND OF THE INVENTION Heretofore adjustable bedframes have relied either on clamps or on bolts and nuts to hold the cross rails together and to maintain the proper spacing between the side rails of the frame. A typical bedframeclamp is shown in US. Pat. No. 2,883,222. With such an arrangement there is no positive determination of the bedframe width and this width must be determined either by measurement or by trial and error. Also, if the clamp becomes loosened it is possible for the side frames to move apart. While bolts provide for thepositive positioning and engagement of the cross rail sections, tools are required to assemble the bedframe and the bolts and nuts are easily lost or misplaced.

It is the primary object of the present invention to provide an adjustable bedframe in which the width of the frame is precisely determined and maintained when the bed is assembled.

It is also an object of the present invention to provide an adjustable bedframe which does not require the use of tools in assemblying the frame and which has no loose or separate components which might become lost.

Other objects of the present invention are the provi-. sion of an adjustable bedframe in which a secure, locked condition is obtained when the frame is assembled, to provide sturdy positive means to vary the width of a bedframe of the Hollywood type, and to provide a practical, easily adjusted width bedframe.

SUBJECT MATTER OF THE INVENTION The above and other objects of the invention which will become apparent in the following detailed description are achieved by providing an adjustable bedframe which consists, essentially, of a pair of side rails, first and second cross rail sections connected to each side rail at the opposite ends thereof, a pair of shoulder rivets or the like in spaced relation on the first cross rail section, and a plurality of pairs of L-shaped slots on the second cross rail section, the slots of each pair being spaced apart by a spacing equal to that of the rivets of the first cross rail sectionand the pairs of slots being spaced from one another by distances equal to the differences in the desired width of the bedframe.

For a more complete understanding of the invention and the objects and advantages thereof reference should be had to the following detailed description and the accompanying drawing wherein there is shown a preferred embodiment of the invention.

In the drawing:

FIG. 1 is a perspective view of the bedframe of the present invention;

FIG. 2 is a top plan view of the bedframe of FIG. 1, showing the cross rail sections in their disengaged relation; and

FIG. 3 is a transverse sectional view taken along the line 33 of FIG. 1.

The bedframe, designated generally by the reference numeral 10, has a pair of side rails 12 which extend the entire length of the bed. A first cross rail section 14 is connected adjacent one end of each of the side rails 12 sections 14 and 16 being opposite one another so as to.

form a pair of first and second cross rail sections at the head and foot of the bedframe when the side rails 12 are'positioned adjacentone another. Each of the cross rail sections 14 and 16 is connected to its respective side rail by a rivet or other connection 18 which permits pivotal movement so that the respective cross rail section may be folded in under or against the side rail, as indicated by the arrows in FIG. '2, so that the bed frame may be easily moved or stored. Legs 22 and casters 24 of suitable known construction are provided in each of the corners of the bedframe. These legs 22 preferably have topflanges 20 and they are secured to and reenforce the cross rail sections and usually limit the arcuate movement thereof.

As can be seen from FIG. 2, as an important feature of the invention, the first cross rail sections 14 are each provided with a pair of shoulder rivets or similar means 28, 28aspaced longitudinally from one another along and suitably secured to the cross rail section adjacent the outer end thereof. The rivets are illustrated clearly in FIG. 3. Each rivet has an end portion 29 which is secured to the cross rail section top flange 14a. The head or shoulder portion 29a of the rivet extends upwardly through the cross rail section 16 and secures this section in the required position. The length of the shoulder portion 29b between the head 29a and section 14a is .at most slightly greater than the thicknesses of section 16a of the cross rail sections 16. v

Each of the second cross rail sections 16 has a plurality of pairs of L-shaped slots or notches 30, 30a, 32, 32a, and 34, 34a. The slots or notches are provided in the top flangeportion 16a of the cross rail section 16 and-have a first portion 36 which extends inwardly at right angles to the longitudinal axis of the cross rail section 16 to approximately the midpoint of the rail section and a second portion 38 extending at right angles to the first portion 36. The width of each of the portions 36 and 38 is slightly greater than the diameter of the shoulder portion (29b) of the rivets. The two notches of each pair are spaced apart by a distance equal to the spacing of the rivets 28 and 28a, thus, the two notches, or slots 30 and 30a of the first pair of notches are spaced apart so that the rivets 28 and 280 can be received simultaneously in these two notches. The first pair of notches 30 and 30a are located on the cross rail section 16 so that when the rivets 28 and 28a are engaged in the inner portions 38 of these notches 30 and 30a the side frames 12 are spaced apart by the width of a single bed. Likewise, slots or notches 32 and 32a are so located that when the pair of rivets 28, 28a

are positioned in these notches the frame is suitable for' use as a double bedframe while the notches 34 and 34a permit the frame to be used as queen sized bedframe. The rivets 28 may be of any suitable construction and their end portions or heads 29a engage the upper cross rail to retain the bedframe in an operative position until the box spring is placed thereon.

It can be seen that to disconnect the cross rail sections 14 and 16 the cross rail sections must be pushed toward one another to move the rivets into alignment with the outer portions 36 of the notches before the cross rail sections can be disengaged from one another.

When a box spring 40 is positioned on the bedframe,

as is shown in phantom outline in FIG. 1, the box spring serves to prevent the side rails 12 from moving toward one another and thus assures that the cross rail sections 14 and 16 remain locked together. The provision of a pair of rivets and a pair of slots assures that the cross rail sections 14 and 16 will remain aligned with one another and provides a secure connection between the two rail sections.

It is seen that preferably each of the side rails 12 has one cross railsection l4 and one second cross rail section 16 secured thereto but at different axial ends of the side rails to achieve a locked engagement position.

The side rails 12 and the cross rail sections 14 and 16 may all be formed of angle stock and end plates 42 may be provided at one end of the side rails 12 for securing a head board to the bedframe, all in the conventional manner. The slots 30 and 34 etc. extend to edges of the cross rail sections and are open in opposite directions as shown in FIG. 2.

It will be understood that while only the best known embodiment of the invention has been illustrated and described in detail herein the invention is not so limited. Reference should therefore be had to the appended claims in determining the true scope of the invention.
